Quote [Old Carthusian]:
However, even though the rarity of the hijack or pilot deviance explanation is significant this particular line of investigation still fits the known facts better.
Correct
: While several theories could fit the facts of plane going 'dark' (cascading electrical, mechanical failures for whatever reason) and turning west off course (airworthiness, compromised avionics issues, cockpit fire -head for the nearest airfield you know) there is the fact of the Immarsat data indicating the plane continued to fly for 7+ hours (and the turn was per-programmed) -
Unless of course the Immarsat data is not a valid incontrovertible fact which raises a whole set of questions as to why it has officially been presented as such.
